3. In an electric vehicle, there is a module called DC-DC, which is also called DC converter. This module inputs 48V and outputs 12V, so you can use it by purchasing a 12V input vehicle inverter.
Of course, if you can buy a 48V input inverter better, but it is estimated that it is difficult to buy and, generally, this module can only provide 5A current, up to 10A, and car lights and other things also need to be used, so it is easy to overload, it is recommended that if you can, buy an additional DC converter, this converter specifically for your inverter power supply, and then if the DC converter can only provide 5A, then So the input of the inverters should be less than 5A, otherwise the module may be damaged. Of course, some DC converters have large current. If there is no place to repair the car, you can go to some electrical stores or ask them to repair it and put in a large current for you, or multiple DC converters can be connected in parallel. In short, don't overload him.
There is a VVVF traction inverter on the urban rail vehicle, which is used for frequency and voltage conversion. When the train is tracted, the high voltage (usually dc750V or DC1500V) is changed into three-phase electricity with adjustable frequency and voltage, which can be used for traction motor. When braking, the three-phase electric energy generated by the inertia-driven traction motor can be converted into direct current feedback to the power grid or consumed through the energy consumption module.
Inverters are mainly used in the field of communication.
Some maintenance tools need AC power supply, DC power supply can not provide AC power, can be provided by inverters.
The direct current generated by the solar energy system is converted into alternating current and input into the power grid.
